On your snatch it looks like you've got a bit of an early arm bend and you're not quite getting full extension. Also, I would stay try to keep your weight on your heels a little longer.
It looks like you're catching the weight out in front of you, but you're strong enough at that weight that you just muscle back into a position over the shoulders.

With the clean, are you releasing your hook grip on the turnover? That would be the biggest thing that my amateur eye sees; your turnover could be a little quicker.

Seems you have made quite a bit of progress since you started! Looking pretty good!

For the snatch, the pull positions are looking good. As Thomas said it seems you are beginning to pull with the arms a bit early. Try to keep those arms long and think about towing the bar up and pushing the bar close using the lats. You want to keep that tension against the bar as you pull under as well (to keep the bar close and pull it into place).

Your turnover was a bit short and that is what cause you to feel a bit unstable. Try to keep that bar close on the way up and really pull it up and back over the neck.

For the clean, the rack position has improved leaps and bounds since the last time. Seems you are able to hold that position for the jerk as well! I would suggest trying to stand up right out of the bottom of that squat. Try not to sit down there too long, make sure your posture is tight and drive right out of that squat.

As always thanks! I have been told I am way too tense, especially in arms, something that would be very difficult to identify in video. Straps during pulls have been suggested. Any other ideas or thoughts? Thanks again.
